Serial No. 488,153 6 Claims. 01. 100-54) going treatment in the mat. Moreover, in the operation of producing stearine and other products, the cakes of tallow are dropped in to the press mat, and in this operation, they knock against the portions of the warp threads of the mat passing over the supporting bars thereof, andv these impacts in time wear the warp threads through and result in the ruination of the mat. Furthergo more, tools are frequently used to pry the mat supporting bars apart at the pressing operation, and this also injures the warp or other threads securing the supporting bars to the mat.

The principal object of this invention is to provide a mat wherein the bars are snugly woven over in the manufacture of these mats on looms. Another important object of the invention is to provide a flexible extension at each end of the press mat, which will effectively serve to absorb the shock of tallow cake impact, before-mentioned, and also serve to retard displacement of the oil content ,of the cake between the supporting bars when the mat is under pressure.

Another important object of this invention is to provide a mat wherein the'supporting bars are woven over' in the manufacture of. the mat wherein the mat is continued on beyond the bars to provide extensions to reinforce the ends of the mat. Another important object of the invention is to I provide a fastener constructed of human hair for I igure 3 represents a fragmentary top planview showing one corner of the mat and the manview of a comner of reinforcing the mat extension at-its end by transverse stitching.

Figure 4 represents a sectional view taken substantially on line H of Figure 3. I Figure 5 represents a sectional view taken substantially on the sameline of Figure 3 on which Figure 4 is taken, but showing the bar removed. Figure 6 represents a perspective view of a pivotal supporting bar.

Figure '1 represents a top plan view of a completed mat showing overhand stitching to reinforce the end extension of the mat.

Figure 8 represents a fragmentary top plan view showing the mat at one end with its extension reinforced by ,overhan'd stitching.

Figure 9 represents a sectional view taken substantially on the line 9-9 of Figure 8.

Referring to the drawings wherein like numerals designate like parts, it can be seen that in the operation of manufacturing this novel mat;structure, an elongated fabric strip is woven as shown in Figure '1, the same being woven in sections having relatively heavy weft threads and sections 6 having relatively light or fine' weft threads, so

that the fabric portion 5 is substantially thicker supporting bars passing therethrough and against which the warp'threads are woven in the manner substantially shown in Figures 3, 4 and 8.

By observing Figure 2, it can be seen that the mat proper generally referred to by numeral 8 has extensions 99 at the ends thereof, which are substantially half portions of the thin fabric' portion 6 of the original strip shown in Figure 1. This mat having been cut from the strip by severing through the intermediate portions of the thin areas of the fabric strips. After the mathas been aciiuired by thus cutting the fabric strips, these extensions 9 are stitched transverse- 1:! as at 10, the stitching 10 passing through the relatively flne weftthreads 11 of the extensions.

While Figures '2, 3 and 5 show'the wefts 11 pierced, bythe transversely extending stitching 10, it hasbeen found that overhand stitching with thread 12 is highly satisfactory and such stitching is clearly shown in Figures 7, 8 and 9.

A closer observation of 3, 4, 5, 8 and 9 will show that the main portion of the mat is made up of wefts 13 substantially heavier than the wefts 11 of the extensions 9, while the warps 14 5 length thereof are of uniform size in the construction of the strip shown in Figure 1, and extend for the full v the extensions 9.

As is clearly shown in Figure 5, by removing the bar 7, a passageway 15 will be provided inwardly of each end of the mat. Obviously by removing the bars, the mats can be economically shipped.

It is to be understood that it is preferable that these mats be produced from human hair, in view of the extreme strength and durability of this material for the purpose.

It can be seen that by using the stitching 10 or 12, the extension 9 will be reinforced so that there is but small likelihood of the bar 7 pulling through the extension.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes-in the shape, size, and

materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

1. A press mat comprising a sheet of woven weft and warp threads, means at each end of the sheet for accommodating mat supporting means, and an extension at each endof the sheet employing the same warp threads and having finer weft threads than the weft threads of the sheet.

2. A press mat comprising a sheet of woven weft and warp threads, said warp threads being individual and free at points inwardly of their ends of weft threads, and a weft at each end of the sheet securing the extremities of the warp threads to define a transverse passageway at each end portion of the sheet to receive a mat supporting member, said last-mentioned weft being.

of finer gauge than the weft of the sheet proper.

3. A press mat comprising a sheet of flexible material, suspension bars at the ends of the sheet, and a flap-like extension at each end of the sheet to protect the portions of the sheet ends through which the bars extend when material is dumped into the sheet. v

4. A press mat comprising a sheetof flexible material, suspension bars at the ends of the sheet, and a flap-like extension at each end of the sheet to protect the portions of the sheet ends through which the bars extend when material is dumped into the sheet, said extensions being thinner than the sheet proper so as to not interfere with the pressing action of the sheet.

reinforcing the construction of these extensions.

6. A press mat comprising a sheet of woven weft and warp threads, said warp threads being individual and free at points inwardly of their ends of weft threads, and a weft at each endof the sheet securing the extremities of the warp threads to define a transverse passageway at each end portion Of the sheet inwardly of the end thereof to receive a mat supporting member.
